Da-Lite Projection Screen At Major Sporting Events
Da-Lite Screen Company is an innovative company based in Warsaw, Indiana. You may have seen their projection screens at a major sporting event, at a retail store or perhaps at a university. Da-Lite tackled the challenge of how to bring projection TV out of the dark and into environments with varying degrees of ambient lighting. Today Da-Lite rear projection screens are seen in corporate boardrooms as well as in upscale home theaters. The technology allows for bright, high-resolution images without sitting in the dark. The Da-lite screen is a high-tech combination of a diffusion coating and a Fresnel screen. The diffusion coating is a substance that is permanently bonded on the screen which is a one-piece acrylic. The process creates a long-lasting product with even distribution of the brightness, no hot spots and no noticeable shifting in color. It is a vast improvement over older screens which used a laminated film or vinyl that can crack, discolor or peel.
The Fresnel screen is a new application for a much older technology. Fresnel was a French physicist who invented a special kind of lens for lighthouses. Instead of using the continuous smooth surface of traditional lens, Fresnel used a collection of smaller lenses placed in concentric annular sections. This allowed the lens to be much thinner, to convey more light and to be seen from greater distances. The Data Pro is one of Da-Lite's screens designed for corporate use. It uses the Fresnel technology and the diffusion coating to provide very high contrast. The screen helps to keep ambient light from weakening the image, especially the black which can often degrade with older versions of projection screens. The screen comes in sizes up to 135 inches diagonally, enough to make a big impression on clients or to conduct training in a large classroom setting. One of Da-Lite's most impressive products is the HoloScreen which is a specialty application of the rear projection technology. Viewers can simultaneously see the image on the screen and see through the screen. The screens, which can be as large as 69 inches by 101 inches, create a holographic image. The screens are in use at major high traffic venues like airports, sporting arenas and some retail stores. For large venues like a university lecture hall Da-Lite has sixteen foot seamless flexible fabric. The material is available for fixed frames and for portable applications such as those used at trade shows and conventions. But you don't have to attend a trade show or a sporting event to benefit from Da-Lite's products. The company also has a line of products for in-home use for upscale home theaters. And they offer advice to help you select the product that is best for you and your home. The first step is to decide what type of screen fits your viewing needs. If your home theater is a dedicated room, meaning that it isn't used for any other purpose, then a fixed screen system is ideal. The system is built directly into your cabinets or even into the wall treatments that control the sound for the room. If the room is used for other things, then a projector lift system allows you to hide the elements when they aren't needed. The next step is the screen size. This is determined by the size of the room. The company recommends that the height of the screen be one third the distance from the screen to the seating area. For example, if your seating is 9 feet away from the screen, you can comfortably view a screen that is 3 feet in height. The surface of the screen is the final step. While distance from the screen helps determine the height of the screen, it is the surface treatment of the screen that controls the viewing angle. A higher viewing angle means that your audience can sit further to the left and right of the center point and still enjoy a clear picture. |
